README
README.mdSmartmeter IR Reader/Writer
This is an implementation of the smart reader concept created by volkszaehler.org.
It has been modified as follows:
- Replaced 13k resistors by 10k (as I have a lot of them in stock)
- Added an RJ11 connector with 4 pins as a connector to the microcontroller unit
This board is intended to interface with a Microcontroller unit via an RJ11 connector.
Schematic & Board Layout
Revision History:
- v1.0: Initial version (Produced: 19.08.2023; not assembled)

Questions
How big is the Smartmeter ir reader PCB?
It measures 27 × 34.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smartmeter ir reader use?
16 parts, built around the SN74LVC1G17DBVR, BAT46W, S8550 and SFH 309. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Smartmeter ir reader KiCad files?
From the chof747/smartmeter-ir-reader repository on GitHub, at the commit this page was made from: the board is smartmeter-ir-reader.kicad_pcb and its schematic smartmeter-ir-reader.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smartmeter ir reader design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
